The watch is described as a handsome, rugged tool watch that is comfortable and wearable, with some anticipating the PVD finish will develop a nice patina. A reviewer notes the dial is borrowed from the Omega Seamaster 300. Some owners find the price steep for a quartz watch, and fixed spring bars are flagged as an issue by one forum user. Overall, owners and reviewers rate the CWC (Cabot Watch Company) SBS 1987 Aged Special highly for its iconic design and military provenance.
Owners widely praise the Knot Watches SAC-40SSV for its Seiko-like finishing and attractive price point, with many appreciating its light feel and the quality of the strap and deployment buckle, though some find it initially stiff. The 40mm size is a point of contention, with some finding it comfortable and a favorite, while others consider it too large and prefer the 38mm variant. A recurring criticism is the small, awkwardly placed crown, which makes winding difficult. One owner also noted poor engraving and considered the watch to be primarily a fashion piece. Overall, owners rate the Knot Watches SAC-40SSV positively for its finishing and value, despite some reservations about the crown design and sizing.
